Is there any reason to not get a soft pack lipo? Obviously they're a bit less expensive.

running offroad, or just jumping and or crashing can take a great toll on soft lipos. i've seen some of mine get damaged by getting hit by other trucks...i've had a couple of mine get damaged by jumping too high and the lipos will then get dented by slightly shifting in the lipo tray...the hardcase lipos are ALOT more durable, and trust me when i say it...it's worth the extra money.

Thanks guys. I'll start doing some price checking. When I was first in the hobby, most all of my packs were soft. The two 2S packs I have now are both hard. Looking at 3S again now, which is what prompted the question.

3S hard-case LiPos are "hard" to come by, but a little bird told me that a certain well-regarded battery supplier is coming out with a 3S/40C/4100mAh pack in a standard-sized (i.e. 2S-sized) hard case, priced at just under $40. The initials of the company are SPC, lol.
The Traxxas "rigid" packs seem to give a good deal of protection too, but I realize that some tracks require a hard case.

I have both soft and hard case lipos. All of my 2s packs are hard case and my 3s pack is a soft case. And the 3s pack is one of my newest packs but it looks like its the oldest. The shrink wrap really gets chewed up easily during off road use and can rip. Mine has started so i had to wrap electrical tape around it.

All of my 2s packs look great and i never have to worry about them. A lot of people dont want to use them because they say its hard to see if the cells are puffed, but trust me, its quite easy to see if the cells are puffed. If they are puffed bad enough it will deform the case or even crack it open.

I wont ever buy a soft case unless it is the only option, and my 3s was.

I run sky lipos and their soft packs have metal insterts on top and bottom under the shrink wrap so they hold their shape really nicely. My sister left a pack plugged in with the esc on in the nephews p2de and ruined a pack so i cut off the wrap to see the metal, its some decently thick stuff. And yes, i did make her buy a new battery.

Yes they are too tall, I have the same problem. With only 30mm clearance its difficult to find any 3s packs to fit the ERBE, hardcase or not. My problem is I dont want anything less than 5000mAh and 40C.

If you talk to the gentleman at SPC he'll tell you that their 3s 50c 5400 mah lipo is designed to fit into a ERBE. They are soft case. I have one hard case and three soft case lipos. My soft are 3s and the hard is a 4s. My first lipos were soft and have done me well for three years now. I don't jump off houses or anything crazy.

I am just a basher and run 3S soft case. I have had no problems. I have had crashes that killed major parts (front bulk head both a-arms shock tower and axles, 45 mph plus into curb) and the soft pack is perfect.
